Working on a sort-of plugin for CMUD. Basically a COM object that creates it own window and does parsing and stuff. However, shy of doing a polling implementation for commands to do in CMUD and/or send to the MUD, is there a way to hookup a custom CMUD event/function to a COM event?

You can define your own #EVENT for CMUD to do something when it gets #RAISE-d.
Its just a matter of detection.

I have not seen anything in the interfaces that makes a plugin aware of events. I believe that plugins never received much attention nor support during the zMud days. As a result, Zugg did not expand any support in CMud. This document https://www.zuggsoft.com/zmud/complug.htm seems most comprehensive on the subject.

It sounds like you've got a COM exe, not just a DLL with blocking calls.

CMud does have its own COM API, so you could run it from the other end... get a handle and force a command or alias to run.

I've more commonly set up a timer that fires frequently to poll the DLL as to progress.

I've built a COM dll (C# class library that is COM visible). Right now I'm using %comcreate("plugin") to create an instance of the object in proc and calling methods/properties on it. Since the CMUD COM objects aren't documented and I don't have a typelib I don't know how to use them properly. Do you have any pointers Tarn?

Actually I think I've figured it out - can use %comcreate("cMUD.Application") to get a reference to the current instance of CMUD (this must be done within CMUD otherwise you just create a new instance of CMUD). Then I reference cmud.exe in the C# project and it creates an interop library from all of the COM type info embedded in the executable. I can then pass the CMUD COM object as a parameter to the plugin init method and voila - I have access to cMUD.Application.

After that is RE to figure out how to call the methods appropriately.

The COM objects have not changed since zMud with some minor exceptions. The documentation is here http://www.zuggsoft.com/page.php?file=zmud/comserve.htm

The exceptions are that portions of zMapper got rolled into the CMud, I think only in the pro version. zMapper's COM interface is documented in its help file.

From within CMud you can get at the COM objects using the Predefined Variables %cmud, %session, and %map.
